STONE-SEPARATOR.

To all whom it may concern:

Be it known that I, ELLERY E. IVORY, a citizen of the United States, residing at Hadley, in the county of Lapeer and State of Michigan, have invented certain new and useful Improvements in Stone-Separators, of which the following is a specification.

This invention relates to an improvement in stone and grit separators to be used in connection with clover hulling machines, and one of the objects of the said invention is to provide a device that may be attachedto almost any of the machines now in use.

A further object of the said invention is to provide a construction that will be cheap to manufacture, efficient in practice and so simple in construction that it may be readily placed in position on the hulling machine without in any way affecting the operation of said machine. The idea involved is to intercept the clover at a point between the feed device and the hulling cylinder and to remove all grit, stone or other foreign material which under ordinary circumstances would enter said cylinder.

With these and other objects in view, the invention consists in the novel construction, arrangement and combination of parts hereinafter described and claimed.

In the drawings, Figure 1, is a sectional view of a portion of a hulling machine showing the separator attached. Fig. 2, is a plan view of the means for feeding the clover to the hulling cylinder. Fig. 3, is an enlarged sectional view showing the construction of the separator in detail. Fig. 4, is asectional view of the cylinder in which the blast fan revolves. Fig. 5, is a detail view of the latch which holds the receptacle for receiving the stone and grit, in position.

In the drawings 1, represents the mechanism for feeding the clover to the hulling cylinder; this feed mechanism is the same as in most machines of this type with the exception that the feed trough is provided with openings at a point where it passes the mouth of the separating attachment. It is to the base of this feeding device that the separator is attached.

The separator consists of a blast fan 1, mounted within a cylinder 2, and a receptacle 3, for the grit and stone located at a point immediately under the openings formed in the feed pan. The cylinder above mentioned extends across the entire width of the Specification of Letters Patent.

feed pan as does the fan which is mounted therein. An opening 4, is formed in the cylinder 2, to allow the air blast to strike the clover as it passes over the openings formed in the feed pan. A portion of the cylinder is bent upon itself and through this bent portion 5, pass screws to secure the cylinder to the feed pan. A lip 6, is formed upon one edge of the cylinder at the opening in the same, and said lip performs a double function, first it acts to direct the air blast and second it acts to hold the grit receptacle 3, in place.

The grit receptacle 3, consists of a piece of sheet metalbent at the point 7, the portion which is struck being made to conform to the shape of the cylinder 2, at the point where it rests against said cylinder. This receptacle extends across the entire width of the feed pan as does the cylinder 2. Another bend ismade in the sheet from which the said receptacle is constructed at the point where sald receptacle meets the feed pan, ears 8, are formed at either end of this bent portion which are provided with an opening to receive a spring pin located on the beam 9, which extends downward from the feed pan and at right angles to the same.

The operatlon of the device is as follows; The clover is fed toward the hulling cylinder along the bed of the feed pan in the usual manner until it reaches the openings formed in said pan. At this point it is struck by the blast of air from the fan 1 which separates it and causes the heavy particles such as small bits of stone and grit to fall into the receptacle 3, the clover being carried over into the huller.

The fan which rotates in bearings formed in either end of the c linder 2, is caused to rotate by. a power heft which passes over a friction wheel which is mounted upon the end of the shaft upon which are secured the blades of the blast fan.

When it becomes necessary to remove the stone and grit from the receptacle 3, the spring pins are pulled out and the said. receptacle may be withdrawn from the side of the machine in the same manner as a drawer and replaced in the same manner. When the receptacle is in position it will be seen that one end will be held securely to the feed pan while the other will be held in place against the cylinder 2. And for the reason that the part which adjoins the cylinder being made to conform to the shape thereof, the

especially adapted for clover hullers it might be used upon almost any harvester with the same result.

I am aware that air blasts as separators are not broadly new and I make no broad claim upon the use of an air blast as a sepa rator.

Having thus describedmy invention, What Iclaim as new and desire to secure by'Letters Patent is;

1 In a stone se arator for clover hulling machines, the com ination of a feed pan, a fan for causing an air blast to separatethe stones from the clover, and a receptacle for receiving said stones, said fan being incased in a cylinder, a'portion of said receptacle being adapted to rest upon said cylinder, said portion being concaved to conform to the shape of the portion of the cylinder upon which it rests.

2. In a stone separator for clovcrhulling machines, the combination, of a'feed pan,,a

cylinder containing a blast falrlooated be.- n'eath-said feed pan and secured to the-said )an by screws passing; through :afiange formed integral with said cylinder,tlie air blasttfronisaid fan beingiadapt'ed't'o come in contact with the clover which is fed over the said pan, by means of openings formed in the pan.

3. In a stone separator for clover hulling .machines, the combination, of a feed pan, a

pass pins which hold the said receptacle to the feed pan.

, r 4. In arstone separatorfor clover hulling machines, the combination, of a feed pan, a cylinder located beneath openings in said feed pan, a blast fan adapted to rotate within said cylinder, a lip formed upon the edge of an opening formed'in the cylinder, said lip being adapted to direct the blast of said fan, and to support one edge of a receptacle for receivingthe stone.

In testimony whereof I have aflixed my signature, in presence of two Witnesses.
